The sudden collapse of tech-focused Silicon Valley Bank (SVB) after a bank run on March 10th makes it the second largest US bank failure ever (after the 2008 implosion of Washington Mutual), with the "tech winter" combining with the cycle of interest rate increases to trigger its demise

On Monday, security guards stood outside SVB branches as queues of people trying to recover their funds formed after US federal authorities said depositors would get all their money back, while HSBC stepped in to rescue the UK arm.

But the trouble didn't end there.

The most-watched Academy Awards in the US was the 70th, held in 1998. This was the year Titanic won 11 Oscars, including best picture, and a record number of viewers checked in to see if Leonardo DiCaprio had defrosted yet.

Getting to know: GPT-4

In robots replacing other robots news, OpenAI – the organisation behind artificial intelligence chatbot ChatGPT – has given birth to a new bot this week: GPT-4.

The youngest child in OpenAI's family has been able to learn from the mistakes of ChatGPT, or rather the mistakes OpenAI researchers made with it, and is said to be less biased and less likely to make up facts than its predecessor. It can accept pictures as inputs from users, and also loves a good novella: up to 20,000 words of text can be fed into it as a single prompt.
